[Cements for fixed prostheses. Traction resistance force]

The cementation is a basic step in the fixed prosthesis rehabilitation. Therefore, it is very important to know the main chemical, physical and biological properties of luting cements. The tensile strength of some dental cements for fixed cast restorations has been studied. Results obtained showed that glass ionomer and zinc oxide-eugenol with Eba are better than the other dental cements. The difference between the data obtained showed to be statistically significant.
